珍珠岩(Perlite)有良好的隔热、防潮、绝缘、吸附性能,除用于建筑材料外,还可作高效除油剂、绝缘体、滤过剂、充填剂、土壤调正剂等。第二次世界大战后才用于工业。七十年代以来,我省先后发现大量矿藏,仅建平县就有十几个小矿,产量日增。对珍珠岩粉尘危害性的研究,国外近年仅有少数文章发表,国内还未见报道。本研究对珍珠岩粉尘危害性、预防措施进行了探讨。经用化学方法、偏光显微镜、红外光 Perlite has good insulation, moisture, insulation, adsorption properties, in addition to building materials, but also for efficient degreasing agents, insulators, filtration agents, fillers, soil conditioner and so on. After World War II for industrial use. Since the seventies, the province has discovered a large number of mineral deposits, Jianping County, there are only a dozen small mines, the output increased. Research on the perniciousness of perlite dust has only been published in a few foreign countries in recent years and has not been reported yet in China. In this study, perilite dust hazard and precautionary measures were discussed. By chemical methods, polarizing microscope, infrared light
